# Java Sum Of Array

The Following Java program add the array element. We use for loop to perform addition with the help of length. It is not a user define program so you cannot enter the length of array and also array element.

## Java Sum Of Array Example

```package pTutorial;
public class SumArray {

public static void main(String[] s) {

// number is a array variable
int[] number = new int[]{ 20, 10, 20, 10, 20};

int sum = 0;

for (int i=0; i < number.length ; i++) {
sum = sum + number[i];
}

System.out.println("Total value of array : " + sum);

}

}
```

### Output

```Total value of array : 80
```

## Java User define Sum Array

This is a user define Java program to perform addition of array element. We use scanner class and scanner class nextInt() method to take input from user.

```package pTutorial;

import java.util.Scanner;

public class SumArray {

public static void main(String[] s) {

System.out.println("Enter the no. of element");

Scanner num=new Scanner(System.in);

int temp = num.nextInt();

int[] number = new int[temp];

System.out.println("Enter "+temp +" numbers");

for(int l=0;l<number.length;l++)

{

number[l]= num.nextInt();
}
int sum = 0;

for (int i=0; i < number.length ; i++) {
sum = sum + number[i];
}

System.out.println("Total value of array : " + sum);

}

}

```

### Output

```Enter the no. of element
2
Enter 2 numbers
10
10
Total value of array : 20
```
